Acne fulminans in patients with a history of Bell's palsy treated with high doses of oral methylprednisolone

Background: Acne fulminans (AF) is rare and is the most severe form of acne vulgaris, especially in men who have a previous history of acne. The disease is characterized by painful ulcerative pustules that are covered by hemorrhagic crusts and are localized in the torso, face, and neck, and can cause systemic symptoms. The cause of fulminant acne is still unknown. Case Description: We reported a 29-year-old man who developed AF after getting high doses of methylprednisolone due to previous Bell's palsy. Patients complained of the appearance of painful and swollen pus lumps on the face, accompanied by fever. Successful management is achieved through systemic and topical therapies provided so that patients experience significant clinical improvement. Early diagnosis and proper management are essential to avoid scarring and minimize the risk of recurrence. Conclusion: Acne fulminans is a severe manifestation of acne vulgaris that more often affects adult men with a previous history of acne. Symptoms shown eruptive lesions, nodules, and painful plaques, and are usually found on the torso, face, and neck with or without systemic symptoms. The pathogenicity of AF is still unknown.
